Creation of the KM3NeT AISBL entity
KM3NeT has taken a major step forward with the creation of the KM3NeT Association Internationale Sans But Lucratif (AISBL), a new international non‑profit entity under Belgian law.
This structure, identified as the best legal framework through the EU‑supported KM3NeT‑Infradev2 project, will streamline and formalise all activities related to the construction, operation, scientific use, and future decommissioning of the infrastructure.
The AISBL was officially signed in Brussels on 18 June 2025 by representatives of the founding members—CNRS, INPP/NCSRD, the University of Valencia, INFN, and NWO‑I— and the Belgian Royal Decree stating the creation of the structure was published in October.
KM3NeT will start operation as an AISBL in January 2026.
Other KM3NeT institutes are expected to join soon as members or observers.
